1 Claim. (01. 334.5)

This invention appertains to archery, and more particularly to a novel sighting device.

One of the primary objects of my invention is to provide a sighting attachment which can be secured to ordinary bows without any change thereto, and which will facilitate the accurate shooting of arrows at different distances and wind velocities.

Another salient object of,my;invention is to provide a bow sight including a vertical rod for attachment to the bow adjacent to the handgrip thereof, and a clamp carrying the sight proper movable longitudinally of the rod, whereby the sight proper can be held at the desired elevation. I

A further object of my invention is to provide means for constructing the clamp, whereby the sight proper can be moved in or out (trans versely of the rod and bow) for proper windage.

A further important object of my invention is the provision of means whereby the clamp and a sight proper can be quickly fastened to or removed from the rod so thatwhen the bow is not in use the clamp and sight proper can be kept in a case against injury.

A still further object of my invention is to provide a bow sight of the above character, which will be durable and efiicient in use, one that will besimple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

With these and other objects in view, them: vention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawing, in which drawing:

Figure 1 is a side elevation of a conventional bow showing my improved sight connected therewith. l

Figure 2 is an enlarged side elevational view of the sight removed from the bow.

Figure 3 is a longitudinal sectional view through the clamp taken substantially on the line 3-3 of Figure 4, looking in the direction of the arrows.

Figure 4 is a view similar to Figure 3 but taken on the line 4-4 of Figure 2.

Figure 5 is a rear elevation view showing a fragment of the sight.

Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter B generally indicates a bow, and A my improved attachment therefor. The bow B is of the usual or any preferred character and size and can be provided at its central portion with a hand grip l0. adapted to be secured to the bow B at the handgrip I0.

of the sight. The clamp can be constructed in various manners, but, as illustrated, the same includes a sleeve or cylindrical body l8 having its an outer end reduced in diameter and externally threaded as at IQ, for a purpose which will be later set forth. The bore of the sleeve extends from one end thereof to the other, and the outer end of the sleeve has formed thereon an inwardly directed annular flange 20. The face of the enlarged portion 2| of the body is provided with a groove 22, which is adapted to receive the sight proper 23, the outer endof which can be provided with a sight opening 24. Threaded on the reduced threaded portion i8 of the sleeve is a nut 25, and this nut is adapted to move toward and away from the sight proper 23 for adjustably clamping the same in position. The sight proper 23 can be graduated in any preferred manner to facilitate setting thereof according to. the velocity of the wind. Likewise, the rod l 5 can he graduated to indicate the proper position of the sight according to the distance being shot.

The clamp also includes a rotatable cap nut 26, and the inner end of the cap nut is reduced and fitted within the flange 20. This reduced end is then flanged or upset, as at 21, so that the cap nut 26 will be rotatably carried by the sleeve. This also positions the nut 25 and prevents displacement of the nut 25 from the sleeve. The bore of the cap nut 26 can be provided with relatively fine threads ifso desired, and in all events the nut receives the threaded shank 28 of the clamp block 29. This clamp block 29 is of a cylindrical shape, and is movable back and forth in the bore of the sleeve l8.

My sighting device A is As clearly shown in Figures 3 and 4, the block for the sight proper 23. Thus, the block 30 can move back and forth without disturbing the sight proper. The block also has formed therein at substantially right angles to'the groove 30 a clamp groove 3! for hooking over the rod- IS. The inner face of the sleeve is grooved as at 32 for receiving the rod, and the rod is adapted to snugly fit within said groove 32.

In use of my device the various parts of the clamp are assembled. asdescribed, and the sight proper 23 is slipped diametrically through the clamp, and is locked in place by the nut 25. The cap nut 26 is loosened so that the clamp block it will be fed from the inner end of the sleeve 29. The clamp block 29 can now be hooked over the rod, and upon tightening of the cap nut 26 the clamp block will bring the sleeve l8 and itself into binding contact with the rod, andthus hold the sight on the rod. Obviously, by loosening the cap nut the sight proper would be raised or lowered to the desired elevation and the raising and lowering of the clamp without disturbing the sight proper 23, and by loosening the nut 25 the sight proper can be moved in or out without disturbing the position of the clamp on the rod.

Changes in details may be made Without departing from the spirit or the scope of my invention, but what Iclaim as new is:

In a device of the class described, a sleeve having an externally threaded reduced portion defining an annular shoulder, said annular shoulder havinga transverse groove therein at one side'of the axial center of the sleeve, a nut threaded on the reduced portion and movable toward and away from said shoulder for securing a member otherwise slidable in said groove,

an internally threaded cap nut having a reduced extension swivelly mounted in the sleeve and holding the first mentioned nut against accidental displacement ofi the sleeve, and a clamp block slidably within and longitudinally of the sleeve and having a threaded shank engaging the threads in the capnut and a lug for gripping between itself and the sleeve the member to which the clamp is' to be attached.
